I didn't realize they had changed the boot disk - that makes the
installation significantly easier and thus the tuxyturvy web site
instructions are pretty much the ones to follow in that event as my
instructions were for dealing with a i586 kernel from the CentOS install
disks (substituting kernel versions of course since the kernel has
incremented since the original release of RHEL-4).
